i have some stuff laying around the house here that i know for sure that i am going to put in. I have an avic n1, rockford punch amps, and kicker ss series speakers that all came out of the 05 sierra that i used to have. my wife has been on me to get the stuff out of the house and this is the best way that I can think of. And yes the truck is in pristine condition. The only things I have had to do is clean the headliner where the sunroof had leaked at some point (I had a local glass shop make sure it wasn't still leaking) and for some reason the leather on the steering wheel was in rough shape so I had that fixed as well.
